One of the most noteworthy iPhone-related events last Christmas was the Appvent Calendar – an initiative started by several developers where a game was made free for a day. I have admired their devotion and grabbed a few titles myself. Apparently, this has been quite profitable for the developers involved as well – only a month had passed before the 3 original founders of the Appvent Calendar teamed up with Openfeint and started the FreeAppADay.com website that followed a similar path. But it seems they are not the only to do so.
